SPIRIT is the name of a charity book project by Scottish photographer John G Moore. Over the course of Spring 2008-Autumn 2009, John travelled the 211 mile John Muir Trail through California’s Sierra Nevada Mountains photographing his journey.

Starting at Yosemite Valley, John travelled south, ending his journey at the highest peak in contiguous USA, Mt Whitney. The book, supported by Adobe, Microsoft, Hasselblad and Lenovo brought John International critical acclaim.
